Coexistence of moyamoya disease and subclavian steal syndrome
摘要
Coexistence of moyamoya disease (MMD) and subclavian steal syndrome (SSS) is an extremely rare condition. We here presented the imaging features of a 50-year-old male with complaints of the severe headache and left upper limb weakness. Computed tomography (CT) angiography showed steno-occlusion of the right terminal internal carotid artery (ICA) and left middle cerebral artery compatible with MMD and total occlusion of the left proximal subclavian artery. Phase-contrast (PC) magnetic resonance (MR) angiography and Doppler ultrasonography (DUS) demonstrated retrograde flow pattern in the left vertebral artery.
